Basic Properties and Some Dynamics Problems of Adaptive Model Reference Systems

We shall discuss the basic properties and some dynamics problems of adaptive model-reference systems which do not use extremum search procedures. The reference model represents some desired process and the adjustment of the controller’s parameters depends upon differences between the coordinates of the plant and those of the model as well as between their derivatives [4]. As compared with other model-reference systems [2,3] those discussed here allow a significantly greater rate of plant parameter change and the adaptive transient process is less dependent on the form of the control signals.
